Some Oasis fans have been able to bag much sought-after tickets for the band's 2025 gigs in the UK and Ireland.
A limited number of fans were able to buy the first batch of tickets during a three-hour window on Friday evening.
Shortly after, tickets were being listed online for more than £6,000 - over 40 times the face value of a standing ticket.
Oasis urged people not to resell tickets at higher prices on websites not linked to their promoter, and said they would be "cancelled".
